Answer:

domain: (-infin., infin.)

range: (-infin., infin.)

Step-by-step explanation:

This is an odd degree polynomial which forms a sideways S shape starting low and ending high. Since nothing restricts the function from having an output for every real number input, the domain and range are (-infin., infin.).

1.5, 2.25, 3.0, 3.75, ...

Natalka [10]

The recursive formula can be used to determine the total amount of time spent making hats based on the total amount of time spent previously is f(n + 1) = f(n) + 0.75

<h3>Recursive functions</h3>

The general recursive function is expressed as:

an+1 = d + an

where

r is the common difference

Given the sequence below

1.5, 2.25, 3.0, 3.75, ...

Common difference = 2.25 - 1.5 = 0.75

Substitute

f(n + 1) = f(n) + d

f(n + 1) = f(n) + 0.75

Hence the recursive formula can be used to determine the total amount of time spent making hats based on the total amount of time spent previously is f(n + 1) = f(n) + 0.75

A biologist created the following graph to show the relationship between the temperature of water (x), in degrees Celsius, and t

Hoochie [10]

Answer:

<em>A.</em><em> There were 400 larvae at 0 degree Celsius.</em>

Step-by-step explanation:

Here,

x = the temperature of water in °C

y = the number of insect larvae in the water

The graph is a graph of quadratic function as it is a parabola and it opens downward, so it has a negative leading coefficient i.e coefficient of x² is negative.

At y intercept, the line or curve passes through y axis. At y intercept the value of x is zero, because on y axis the value of x is 0.

As the y intercept in this case is (0, 400), so at y intercept value of x is 0 and y is 400.

Therefore, at y intercept or at 0°C there were 400 larvae.

I have a right triangle. The hypotenuse is 12. The base is 7 and the other side is 9.7. The sin(x) is 0.014. Cos(x) is 0.99 and

Zanzabum

Answer:

$\sin(x)=\frac{\sqrt{95}}{12}=0.8122$

$\cos(x)=\frac{7}{12} \approx .5833$

$\tan(x)=\frac{\sqrt{95}}{7} \approx 1.3924$

$x=\sin^{-1}(\frac{\sqrt{95}}{12}) \approx 54.3147$ degrees.

I don't know what you want to round to but I can tell you are rounding...

Step-by-step explanation:

Soh Cah Toa is the acronym we will use to help us solve this.

This says sine is opposite over hypotenuse.

It also says cosine is adjacent over hypotenuse.

And finally tangent is opposite over adjacent.

Note: Opposite and adjacent can change depending on how you are looking at the triangle, like which angle you are referring to.

Let's look at x:

The side that is opposite, not touching, the angle whose measurement is x, is the side that has measurement $\sqrt{95} \approx 9.7$ .

I see you already found this measurement. This is really good. I might use the exact value for now and round at the end.

The side that is the hypotenuse no matter the angle you are referencing is always going to be opposite the angle whose measurement is 90 degrees. It is also the longest side (since it is opposite the largest angle). This side has measurement 12.

The hypotenuse will be one of the sides touching your angle you are referencing. The other side that is touching your angle is the adjacent side. This side has measurement 7.

Anyways let's plug into the definitions we had above:

$\sin(x)=\frac{\sqrt{95}}{12}$ (O/H)
